Y, Overview before opening the dura. The postauricular approach offers the potential for providing retrosigmoid, presigmoid, and far-lateral exposures and can be used to access the infratemporal and pterygopalatine fossae, the orbit, and the subtemporal areas. In this case, the exposure extends from the retrosigmoid area forward to the orbit. The maxillary sinus has been opened below the orbital floor. Z, Overview of exposure after opening the dura.
